MapR Installer

You must download and run the MapR Installer setup script before you can start the MapR Installer web interface or issue MapR Installer Stanza commands.

The MapR Installer web interface simplifies the installation of a MapR cluster. After taking you through the process of selecting services and configuring the cluster, the installer installs MapR software. You can use the MapR Installer to install:

New-feature releases, such as 6.1.0 and 6.2.0
Maintenance releases, such as 6.0.1 and 6.1.1
Ecosystem components, such as Spark, Hive, and HBase – or other components contained in a Ezmeral Ecosystem Pack (EEP)

Before you begin, review the MapR Installer Prerequisites and Guidelines, which describe user, node, and security requirements for using the Installer. For cluster-planning information, see Planning the Cluster.

Steps for Setting Up and Running the MapR Installer

To set up and run the installer, complete the following steps:

Select a node from which to run the MapR Installer. The node from which you run the MapR Installer does not need to be one of the nodes on which you plan to install the cluster.
Download the mapr-setup.sh script. Choose one of the following options:
- Download the setup script directly from package.ezmeral.hpe.com to the node that will run the MapR Installer:
  MapR 6.0.0 and later
  IMPORTANT To access the Data Fabric internet repository, you must specify the email and token of an HPE Passport account. For more information, see Using the HPE Ezmeral Token-Authenticated Internet Repository.
```
wget --user=<email> --password=<token> https://package.ezmeral.hpe.com/releases/installer/mapr-setup.sh -P /tmp
```
  MapR 5.2.2 and earlier (for more information, see Selecting an Installer Version to Use)
```
wget https://package.ezmeral.hpe.com/releases/installer-v1.11.0/mapr-setup.sh -P /tmp
```
- Download to your local workstation, and copy to the node that will run the MapR Installer:
  1. On the Download Page, click Download, and save the setup script to a location on your workstation.
  2. Use a tool such as SCP to copy the file to the node that will run the MapR Installer:
```
scp mapr-setup.sh user@server:/tmp
```
Change the file permissions so that you can run the file.
```
chmod +x /tmp/mapr-setup.sh
```
Run the mapr-setup.sh script to configure the node to run the MapR Installer. Run the following command as the root user from the directory that contains the script. You must include your HPE Passport email and token and specify the name of the internet repository. The Installer remembers this information for later use. The script prompts you for some information. If you have not used this script before, consider reviewing Using mapr-setup.sh to be prepared.
```
/tmp/mapr-setup.sh -r https://<email>:<token>@package.ezmeral.hpe.com/releases/
```
Start the MapR Installer. Open the MapR Installer URL:
```
https://<Installer Node hostname/IPaddress>:9443
```
You are prompted to log in as the cluster administrator user that you configured while running the mapr-setup.sh script.

Other Tasks You Can Perform with the MapR Installer

Once the initial installation completes, you can use the same MapR Installer URL to upgrade the cluster, apply a patch, or add nodes and additional services:

Use this option	To
Extend Cluster	Add a host to an existing cluster.
Incremental Install	Add or upgrade services that are already installed on the cluster.
Maintenance Update	Update your cluster to a new patch version of MapR core or apply a patch.
Version Upgrade	Upgrade the cluster to a newer MapR release, apply a patch, and upgrade services that are already installed on the cluster.
Shutdown	Stop MapR services on the cluster.
Uninstall	Remove existing MapR software before proceeding with a new installation.

NOTE The MapR Installer definitions are updated frequently. See Updating the MapR Installer to get the latest ecosystem components and MapR software.
